Ailing Woods gets well with gutsy opening 67

He was sick to his stomach, his ankle ached and the wind was not being kind at Poipu Bay Golf Course. So all Tiger Woods did was gut out an impressive 5-under 67 that gave him a three-shot lead over Phil Mickelson at the PGA Grand Slam of Golf.

POIPU BEACH, Hawaii (AP) -- Tiger Woods overcame a stomach virus and labored to a 5-under 67 Tuesday to take a three-stroke lead over defending champion Phil Mickelson after the opening round of the PGA Grand Slam of Golf.

Woods, seeking a record sixth Grand Slam title, was visibly affected by a virus that forced him to miss Monday's pro-am. But, he managed to get through the round in muggy conditions with temperatures in the 80s at the oceanside Poipu Bay Golf Course.

Michael Campbell shot a 73 and Vijay Singh had a 75 in the 36-hole event for the winners of this year's majors.

Woods had an up-and-down start, but got stronger as the round went on. He had a bogey-free back nine that included four birdies and punctuated his round with an 8-foot birdie putt at the 18th.

He birdied Nos. 10 and 11 to tie Mickelson, and took the lead on the par-4, 501-yard 16th when Mickelson hit his second shot, a 3-wood from 235-yards, left into a heiau, or sacred worship grounds built by ancient Hawaiians.

Sweating profusely before hitting his first ball at the practice range, Woods took a swig of some stomach medicine about 15 minutes before teeing off and looked uncomfortable during the round. However, the ankle he twisted last weekend while defending his title at Phoenix Dunlop in Japan, didn't seem to bother him.

His drive on the opening hole found a fairway bunker, and his second shot caught the lip of the trap and traveled only 6 feet.

"Great start today," said Woods, who bogeyed the hole and then got sick.

"Once I threw up in the bushes behind the first green, I felt a lot better," Woods said.

He was rushed to a restroom in a golf cart after teeing off on the uphill, 524-yard No. 2, which was birdied by all four players.

Woods, who earned an invite to Kauai with his wins in the Masters and British Open, had four birdies and three bogeys on the front nine and made the turn at 35 with Campbell and Singh, two strokes behind Mickelson.

Mickelson, who capped his spectacular season last year with a 13-under 59 to win the Grand Slam by five strokes over Singh, stumbled late in the round with bogeys at Nos. 16-17, allowing Woods to move into the lead.

Lefty didn't leave San Diego until Tuesday morning and arrived at Poipu 11/2 hours before his round.

Campbell, a hero in New Zealand after winning the U.S. Open in June, bogeyed three of the last four holes.

Singh, selected an alternate in the event based on his performance in this year's majors, was in a three-way tie, two strokes behind Mickelson at the turn, but had a quadruple bogey on the 193-yard 11th hole.

The world's second-ranked player carded a 7 after his 5-iron tee shot landed in the water, short of the green. His drop, using a wedge from 50-yards out, hit the bank and rolled into the pond.

He then bogeyed the next two holes and finished the back nine with a 40.
